how to run virtual server

["vikas kashyap" <k_vikaskashyap@xxxxxxxxxxxxxx>]

  Recently I installed ipvs 1.0.9 on my network.I wrote a sample client & real 
server program.Client gives a number & real server has to find its cube.
                  But though my virtual server is forwarding the request to 
real server ( I got to know it through tcp dump ),the real server isn't 
responding.

So can anyone please give me a sample client & real server program & the 
necessary steps to configure the virtual server ? Please hurry.
